Composition for improving microflora containing herbal medicine extract as active ingredient

ABSTRACT

Disclosed is a composition for improving microbial flora containing a herbal medicine extract as an active ingredient, wherein the composition can inhibit the growth of harmful bacteria and promote the growth of beneficial bacteria.

TECHNICAL FIELD

The present disclosure relates to a composition for improving microbial flora, comprising a herbal medicine extract as an active ingredient.

BACKGROUND ART

The human body is a complex and active ecosystem, and various microorganisms exist in the gastrointestine and skin of the human body. A microbial community existing in the gastrointestine and skin, etc., is called microbial flora, and 500 to 1000 or more different microorganisms coexist together to form the microbial flora. Intestinal microorganisms present in the gastrointestine synthesize substances such as vitamins and supply them to the human body, and play a role in suppressing infection by pathogenic microorganisms introduced through contaminated food.

Microorganisms on the skin affect the human physiologies such as human growth, nutrition, immunity, resistance to pathogenicity, etc., and play a role in blocking the invasion of external microorganisms, particularly pathogenic microorganisms. In addition, microorganisms residing on the skin are known to control the pH of the skin and perform a skin barrier function, and to affect a skin condition by changing the skin lipid content. For example, it is known that atopic patients have dry and cracked keratinized skin due to a decrease of the ceramide content in the stratum corneum, and Staphylococcus aureus inhabiting the skin is increasing extremely.

Since there are microorganisms that have a beneficial effect on the human body, it is necessary to promote the growth of beneficial bacteria while suppressing the growth of harmful bacteria, rather than simply removing (sterilizing) all microorganisms.

The present inventors completed the present disclosure as a result of conducting research for improving the microbial flora using natural products.

The pre-cultured S. aureus KCTC 1916 strain was inoculated into 20 ml of TSB liquid medium so that O.D.₆₀₀ became 0.05, and 200 μl (1% (v/v)) of Carthami Fructus extract extracted with methanol was added. In the control group, methanol was added at a concentration of 1% (v/v) instead of the Carthami Fructus extract. Then, the growth degree was confirmed by measuring the absorbance at 600 nm using an Optizen 2120 UV plus spectrophotometer (Mecasys Co., Ltd., Daejeon, Korea) every 1 hour while culturing at 37° C. and 250 rpm.

Also, a stock of S. epidermidis KCTC 1917 was cultured in the same manner as above to measure the growth rate, except that the stock was cultured by spreading on an NB (nutrients broth, Becton Dickinson and Company) agar plate.

As a result of the measurement, as shown in FIG. 21, it could be confirmed that by the Carthami Fructus extract extracted with methanol, the growth rate of S. epidermidis was increased and the growth rate of S. aureus was decreased. Specifically, the doubling time of S. epidermidis was decreased by about 36.14% in the group treated with the Carthami Fructus extract (49.31 minutes) compared to the control group (77.22 minutes).

On the other hand, the doubling time of S. aureus was increased by about 1.28% in the group treated with the Carthami Fructus extract (35.57 minutes) compared to the control group (35.12 minutes).

12-3. Changes in Growth of Skin Resident Microorganisms by Carthami Fructus Extract Extracted with Methanol

Microorganisms were pre-cultured in the same manner as in Example 12-2, and the pre-cultured S. aureus KCTC 1916 strain and S. epidermidis KCTC 1917 strain were mixed and inoculated in 20 ml of NB liquid medium so that O.D.₆₀₀ became 0.05. 200 μl (1% (v/v)) of Carthami Fructus extract extracted with methanol was added, and in the case of control group, methanol was added at a concentration of 1% (v/v), followed by incubation at 37° C. and 250 rpm for 3 hours. Thereafter, 100 μl of the culture solution was spread on the NB agar plate, and cultured at 37° C. for 24 hours to confirm the colony forming unit (CFU).

As a result of the measurement, as shown in FIG. 22, it could be confirmed that by treatment of the Carthami Fructus extract extracted with methanol, the growth of S. aureus was inhibited and the growth of S. epidermidis was increased.

12-4. Changes in Growth of Skin Resident Microorganisms by Carthami Fructus Extract Extracted with 95% Ethanol

Except for the treatment using Carthami Fructus extract extracted with 95% ethanol at different concentrations (0 to 0.5 g/l), the growth degree of microorganisms was confirmed in the same manner as in 12-3 above.

As a result, as shown in FIG. 23, it could be confirmed that by the treatment of the Carthami Fructus extract extracted with 95% ethanol, the growth of S. aureus was remarkably decreased, whereas the growth of S. epidermidis was significantly increased.
